CHRISTOPHER RIESSNER, OF NEW YORK, N. Y.

LANTERN.

SPECIFICATION forming part of Letters Patent No. 316A86, dated April 28,1885.

(X0 model.)

To all whom it may concern:

Be it known that I, CHRISTOPHER Bruss- NER, of New York, in the countyof New York and State of New York, have invented certain Improvements inLanterns, of which the following is a specification.

This invention relates to lanterns; and the invention consists incertain details ot'construction, as hereinafter more fully set forth.

Figure 1 is a perspective view of the lantern complete. Fig. 2 is atransverse vertical section on the line 3 y of Fig. 8. Fig. 3 is atransverse horizontal section on the line 00 00 of Fig.2. Fig. 4 is aface View of one of the side plates or panels shown detached. Fig. 5 isa view of the strip from which the side frames are formed.

To construct a lantern on my improved plan I provide four pieces ofheavy or plate glass of the form shown in Fig. 4, and preferably havingtheir edges beveled, as shown in the several figures. Each of theseglass plates A, I inclose in a light metal frame, which consists of anarrow strip of thin sheet metal of sufficient length to extend entirelyaround the edge of the plate. This strip b has notches cut in itsopposite edges at points corresponding with the corners of the plate A,as shown in Fig. 5, and is bent along its center in the line of itslength at such an angleas to fit the beveled edges of the plate A, asshown more clearly in crosssection in Fig. 3. This strip 22 is thenapplied to the edge of the plate by bending the strip at each of thepoints where the notches e are cut, and carrying it around the edge ofthe plateA and bringing its ends together at one corner, where they areunited and held fast by solderingthem together, thus, as it were,providing each glass plate with a metal binding all around its edges.Ithen unite four of these bound glass plates or panels A to form thebody of the lantern by simply soldering them together at top and bottomat each corner, and then secure to the top a perforated metallic topsection, I, the lower end or edges of which are made flaring to fit overand upon the metal strips 11, to which they are securely soldered allaround,and over the open upper end of thisI secure two curved plates,JK,to guard or protect the hand from the heat and smoke of the lamp. Asshown in Fig. 1, the outer plate, K, has its ends 0 1 extended down onthe sides of the section I farenough to permit the ends of the wire bailH to pass through a hole in both and be turned up on the inside, asshown in Fig. 2, thereby fastening these parts securely together, sothey cannot separate and let the lantern fall, even if it should becomeunsoldered at that point.

The lower section of the lantern consists of a rectangular oil cup orreservoir, B, corresponding in size transx ersely with the lower end ofthe body above, as shown in Figs. 1 and 2, the outer walls of thissectionB extending for some distance above the top of theoilchamber T,and serving to form a connection between the oil cup or reservoir andthe transparent body above, as shown clearlyin Fig. 2. This upwardextension of the side walls of the section B has aseniicircular groove,d, formed in it all around, and in this is formed a series of slots, 0,as shown in Fig. 1, for the admission of air. I then line this slottedportion all around with a strip of finely-perforated sheet metal orwire-gauze, L, the upper edges of which are turned outward to connectwith the inturned upper edge of the walls of 13, thereby forming a spaceor chamber, 0, all around the sides, as shown in Fig. 2, into which theair enters through the slots 0, and from which, it escapes through thesmall perforations in the lining L. By these means I secure an abundanceof air to support combustion, and at the same time prevent theflickering of the flame by drafts of air, thus insuring a steady flame,and enabling the lantern to be carried and moved aboutwithout affectingits light.

As shown in Fig. 2, the burner used has its wick-tube surrounded by aperforated cone, slotted at its top for the flame, which produces a goodbright flame from coal-oil with out the use of a chimney. Thisburner,being well known to the trade, need not be further described, andis only referred to because I find it to be the best known to me for usein this connection, more especially as it is desirable to make theselanterns as small as permissible, thereby bringing the glass, whichstands inclined,nearer the flame than is usual with the old-styleglobes, and which renders it important that a good clear flame be used,in order to prevent obscuring the light by smoke or soot on the glassplates.

I connect the upper and lower sections of the lamp by a hinge, a, asshown in Figs. 1 and 2', and at the opposite side I solder rigidly tothe strip 1) a fiat spring, h, which has its lower end bent to coincidewith the groove or indentation d in the walls of section B, and whichthus forms a spring-catch which yields as its lower curved end ispressed upon the upper edge of section B, and when the parts are pressedtogether springs into the groove d and holds the parts securelytogether.

In making the larger sizes of these lanterns I further strengthen theupper section or body by fastening in each corner a narrow anglestrip ofmetal, a, as shown in Figs. 2 and 8, they being soldered to the metalbinding b of the plates A at the bottom and to the metal section Iabove.

The metal portions for the cheaper grades oflanterns will be made of tinand be japanned. For the better grades they will be made of brass andthe finer ones will be nickel-plated.

By using plate-glass or thick heavy plates,

Q as shown, I dispense entirely with the wire guards ordinarily used, asthis glass is strong enough without them, and by beveling the edges ofthe glass plates A, as well as by making them narrower at the top thanat the bottom, I enhance the appearance of the article.

It is obvious that the form of the lantern may be changed by uniting sixor eight or any desired number of these panels, they be ing madecorrespondingly narrower, and the lower section being made of a form tocorrespond, but that would increase the cost, and therefore wouldseldom, if ever, be found desirable.

Having thus described my invention, what I claim is- 1. Atransparentbody for a lantern, consisting of a series of glass plates, A, eachbound bya metal strip, 7), extending around the edges of the plate, theseries of plates then being secured or fastened together, substantiallyas described.

2. A lantern consisting of the transparent body composed of the panelsA, bound around with the metal strips b, united, as described, with thesection-B, consisting of the oil-reservoir T, having the slots 0, andthe perlomtwl lining L, arranged above the oil-chamber and surroundingthe burner, as shown, said section being hinged to the body at one side,with the spring-catch h at the opposite side, all being constructed andarranged to operate substantially as described.
